Abstract

A method of transporting a client signal across an optical transport network (OTN) comprises dividing (201) a received client signal into a plurality of parallel signals at a lower bit rate. The parallel signals are mapped (202) into a respective number of optical data units (ODUs), each having payload bytes and overhead bytes. Each ODU is mapped (203) into a respective optical transport unit (OTUs) having payload bytes and overhead bytes. The OTUs are transmitted (204) across respective optical carriers of a super- channel, the optical carriers of the super-channel being synchronously modulated. Optical channel control information is inserted into the overhead bytes of the ODU and/or OTU. The optical channel control information is used to manage and/or control the transport of the client signal using the super-channel.
